Gartner delivers technology research to global technology business leaders to make informed decisions on key initiatives.
A framework for managing access to data that involves three layers or schemas: the external or programming view, the conceptual or data administration view, and the internal or database administration view. Such ideas were developed by an American National Standards Institute/Scalable Processor Architecture subcommittee in 1971 but received little practical implementation by database management system (DBMS) vendors. The principle is that the conceptual schema consists of business rules derived from a semantic data model, which provides independence between programs and data structures. The emphasis has since shifted to computer-aided software engineering (CASE) tools and “repository” standards.

3D LCD technology enables users to view 3D images either with 3D glasses (stereoscopic LCDs) or without 3D glasses (autostereoscopic LCDs). For smaller screen sizes (typically up to 10 inches), directional backlight 3D is a cost-effective technology that uses the LCD’s backlight to change the viewing fields for the left and right eyes sequentially, thereby creating image depth.
Industry:Technology
Collaborative project among various standards bodies, such as the American National Standards Institute (ANSI), Telecommunications Industry Association (TIA) and enterprise application integration-41 (EAI-41), under the auspices of the ITU, which is developing global specifications for the evolution of 3G technologies. 3GPP focuses on the evolution of GSM and WCDMA, while 3GPP2 focuses on the evolution of cdma2000.

3G wireless networks support peak data rates of 144 Kbps at mobile user speeds, 384 Kbps at pedestrian user speeds and 2 Mbps in fixed locations (peak speeds), although some initial deployments were configured to support only 64 Kbps. The International Telecommunication Union (ITU) coordinates 3G standards through its International Mobile Telecommunications-2000 (IMT-2000) project and incorporates the key standards bodies, Third-Generation Partnership Project (3GPP) and 3GPP2. See also High-Speed Packet Access (HSPA) and Long Term Evolution (LTE).

Thin provisioning allocates physical capacity from a virtualized pool of storage to logical volumes on a just-in-time basis (also known as allocate on write), rather than preallocating large amounts of capacity in anticipation of an application’s needs. It eliminates instances of stranded capacity and improves storage utilization rates, often into the 75%-to-80% range.

Thin client is used to describe a type of client/server computing in which applications are run, and data is stored, on the server rather than on the client. Because the applications are executed on the server, they do not require client-resident installation, although the graphical user interface and some application logic may be rendered to the client. A common misperception is that a thin-client application requires the use of a thin-client device (i.e., a stripped-down desktop machine that costs less to buy and maintain than a regular PC). However, while thin-client applications enable such devices to be used, they do not require it. In fact, more than 85% of devices used to display thin-client Windows applications are regular PCs, typically configured with both “fat-client” applications and access to thin-client ones.
Industry:Technology
An output device that creates the desired image one dot at a time, using point-specific heat to transfer ink from a ribbon to a receiving substrate.
Industry:Technology
Thermal printing is a process that uses the heat from a thermal print head to darken chemically treated paper. Thermal paper is coated paper that reacts to heat. When the paper passes through the printer assembly, it comes into contact with a thermal print head array and the heater elements turn on to activate the thermal coating, creating the image. The only supply item used is thermal paper.
Industry:Technology
Software used for finding units of textual information such as documents by matching a user’s search terms to those in a full-text index derived from the collection of textual units.
Industry:Technology
The process of extracting information from collections of textual data and utilizing it for business objectives.
